v purpose indicated susceptible o f A H MICHAEL A. Briana outrun-onto} ORGANIZED MECHANISM FOR FLANGING PLATES.

I Application filed February 23, 1926. Serial No."90,200.' I

My present invention has to do with the Hanging of plates, and contemplates the pr0- vision of a peculiar and .advantageous organized mechanism through the medium of which boiler and tank plates may be'expeditiously and easily flanged.

The invention also contemplates the provision of an organized mechanism for the v f application to a standard punch andshear,

Other objects and practical advantages of the invention will be fully understood from the following description and claim when the same areread inconnection with the drawings, accompanying and forming part of this specification, 1n wh1ch:

Figure 1 is a. view, partly in side elevation'and partly in section, illustrative of the organized mechanlsm constituting the best practical embodiment of my invention of which I am cognizant. 7 I

Figure 2 is an end elevation of'the same. Figure 3 is a fragmentary or detail view, partly 'inelevation and partly in section,

showing the clamp wedge of my improvement and the parts adjacent thereto.

Flgure 4 is a side elevat on of the former comprised in myimprovement.

Figure 5 is a top plan view of the said 1 or movable head of punch, designated by3;

and the mechanism' further includes a clamping means for holding plates in proper position incident to the flangmg operation, the said clamping means being made up of an upper block 4:, a lowerfblock 5, andv a rectilinearly movable clamp wedge 6 between said, blocks. As will be readily understood by comparison of Figures 1, 2 and3, the

blocks 45 and 5 and the clamping wedge 6 are held together by dovetail means designated byj7, Thesaid dovetail connecting means is so d sposedthat when the wedge 6 is moved rect1linearly,.the height of the three parts 4, 5 and 6 is increased or diminished accord ing to the direction in which the wedge 6 is moved. A rack 8 is provided on the wedge 6,

Figure 1', and adapted to be driven by a standard air motor or-any other appropriatedriving means. As shown in Figures 1' and 4, the former 2 is provided with a tapered bottom 10,designed to facilitate the passing of a'plateto be flanged under said former.

The former2 is preferably of steel for obvious reasons, and it is arranged as shown in a and meshed with said rack is a spur gear'9. having by preference the'square portion m,

Figure'Q relative to the portions 11 and 12 of the anvil. g

Aside from the elements herein explicitly referred to, the associated elements illustrated may be, of'the construction illustrated or of any other construction and arrangement consonant with the purpose of my in-,

vention.

It will be apparent from the foregoing that with my novel organized mechanism,

boiler and tank plates and the like may be flanged to a ninety degree angle, and this ac- I curately and expeditiously. V

It will further be appreciated that my novel organized mechanism is adapted particularly for fianging long plates which'by reason of the construction of. v I have entered into adetailed description of the construction and relative ar rangement of the parts embraced in the presof the'mechamsm'may be handled with facility for the flanging there- 5 ent and preferred embodiment of my inveni tion in order to impart a full, clear and exact understanding of the saidembodiment. I do not desire, however,to be understood as confining myself to the specific COI1SlZIl1Cl2l0Tl, and

relative arrangement of parts as, disclosed,

my invention being defined by'myappended claim within the scope of which changes in structures and changes in. arrangement may be made without departure from my invention.

Having described my invention, what I claim and desire to secure by Letters Patent, l

The combination in an organized plate flangmg machine, of an anvil, aformer,and I clamping means for holding plates in proper position incident to the fianging operation, the said means located in spaced relation from the vertical plane of the former and above the anvil, and being made up of upper and lower blocks, a reotilinearly movable wedge interposed between and dove-tailed to said blocks and having a rack, and a gear disposed in one block and meshed with said rack for the transmission of rectilinear move- 10 ment to the wedge.

In testimony whereof I aflix my signature.

MICHAEL A. BURKE.
